A. y y

Slidahly'inounted on the exterior'of each "door` section near* the free Iedge thereof is a vertical 'sliding inethber 23 having acentral extension 241"`consideraybly` nartower than the "door Section, extending horizontally` along the (Iiifiper 's'uril'acel of thev door section* and slidmounted in' guide straps or loops25.

It willbe seen thatl by' rotating"ly the 44cam 27 in.y one direction, it'will` engagebne of the .ghideinernbers 25 "and'forcethe membei," 231away fro1n"`the` hingedffend of the "door section to'thefpo'siton illustrated by l the showing of the upper yright-handdoor s'eetioii'in 'Figi By swingngl the I'cam 27bymeans off thelhandlel28aa half turn,

the cam will Aengage the other guide strap for moving' the slidable member 231toward the hinged end of the door.as illustrated by the showing of the middle right# hand door section in Fig. 1.

Received in the lower door frame member 14, at the central portion thereof, is a socket 29, having at its upper edge laterally extended yflanges 30, countersunk in the angle irons 34, having vertical flanges'parallel and secured to the central flange of the T-iron, and having 4their other lianges ex'- tending in opposite directions from the cen'- tral Hange of the T-iron substantially .paral` lel'with the base flanges A of kthe T-irons.

It is well known that the surfaces of the flanges A adjacent to the central liange of the T-irons are, inthe ordinary construction of I-irons, slightlyA beveled, as shown y in Fig. 8.

cThe central flange of the T-iron vextends downwardly between the other parts of said -post and is received in the socket, 19, asV

shown in Fig. 4.-

Y lThe flange has in it a slot 35 above a notch or recess 36 in the member 14, so-that a hook 37 pivoted tolthe T-irons may be inrvsertedthrough said slot withv its hook member engagingthe undery surfaceof the lflange 30, as shown in Fig. 5.'

`'Secured to the angle-irons 34at the upper ends thereof, are spaced upwardly extending bars 38, having at their vupperjends alined, vertical, elongated slots 39 inwhich isniounted a bolt 40v pivotally extended lthrough lthe eye 41 of an eye-bolt 42, which is rotatably mounted in the top frame member a0.

Y means of a hook or the like 43, secured to l y y l *simple and there 1s no danger ofthe' slidcef 'l' f provided at, their lower edges` with vstrips 45 whichextend downwardly and overlap the .vupperfedge of the next lowery door section permit the raising of the post thus described, after which the post can be swung upwardly I and laterally toposition adjacent to'` the.4

under surface of the top ofthe car. andl can be supportedy in such raised position by thev frame of the car.-

4It is noted 'thats the post is pivotally and slidably mounted on the eye,bolt4 2 .Y Each ofthe central and .upper door sections are when the ydoors are closed.

nach lower andmidaie slidable' heater' 1t will thus be seenl that the slot 39 willf 23 has at its upper edge a strap 46 arranged to extend upwardly and overlap the next- 'series of door sections,` is moved from'the position shown on the upper right-hand door section in Fig. 1 to position shown by the illustration of the` middle `right-*hand door section in saidligure.

It willbe notedthat the stops 48 limitthe downward movement of the handle'28.

The Iupper door section, which is now unwardly into the'car. The next lower section 'may then be manipulated inthe same way, yand soon.

It will be noted that "afteriopefra'ting the cams on all ,thev door sectionsin onel series, the door sections in that series may be swung inwardly or outwardly i as a unit. y

The lower door section'cannot be swung inwardly, however, until after the upper door sections have been swung inwardly or at the same timeztherewith, and th'eupper door sections cannot swing outwardly, ex-

lower door vsections are swungoutwardly.

It willbe noted that one or more of the `doorsections can be opened at a time without interfering or unlocking or releasing the other door sections. Y l

It willbe noted that themernbers 45 make a grain tight joint, and that the vslidable `members in connection with vthe movable -post also make a graintight joint. i ,1l

l/Vhen the doors are notin use, or are not needed, they may be swung back lagainst the inside of thecarl wall, and the movable post may be swung llaterally and upwardly, as

shown by the dotted lines, and held in position bythe member 43,- asshown in Fig. 6.

The doors and parts thereof are Vpreferably madeof metal, so that they are comparatively thin, and are verystrong durable. Y, I i The Llocking device yfory the doors is very able members 'becomingA released while: the car 1s loaded, .on account ofthel fact that the Apressure ofthe load causes the slidable members to frictionally engage the uprightjpost.

Attention is vcalledto the simplicityof the construction of the upright post, which is made of an ordinary T-bar having two angled irons secured thereto.

'der consideration, may then be4 swung in-` ceptuntil aftervor at the same timewhen the i When not in use the parts take up very little room, and do not substantially decrease the capacity of the car.

Some changes may be made in the arrangement and construction of the various parts of my improved grain door Without departingfrom the essential features and purposes thereof,l and it is my intention to cover by this application any such changes which may be included Within the scope of my claims.

I claim as my invention:

l. In a grain door, a frame, a vertical central post fixed therein, a plurality of doors disposed in vertical succession hinged to the inner side edge of the frame and adapted to swing through an angle of 270 degrees, said doors being of such length that their free ends may be swung past the postV in either direction, and means for forming a grain tight joint between said Jfree ends and the post and for locking same together.

2. In a grain door, a frame, a vertical central post fixed therein, said post being adapted to be swung to a position above and adjacent to said frame, a plurality of doors disposed in vertical succession hinged to the inner side edge of the frame and adapted to swing through an angle of 270 degrees, said doors being of such length that their free ends may be swung past the post in either direction, and means for forming a rain tight joint between said free ends an the post and for locking same together.
